lin ordinary lubricators of this classl 'each i of the. upper sight-feed brackets contains,

nearltheontletpoint into the Oil-pipes which 6 5\ lead to the'cylinders, an outlet-nozzle with an exceedingly-small opening,which, in con?, nectionvvith the vequalizing-pipes M,s erves' in" the usual'manner to equalize. the pressure Owing toptlie fact that 47o the steam-supply for thelubricator is directly f ,'.frorn'thelooiler it is'evrdent'that the escape.

OYE steam 'and oil .through'the upper sight feed bracketsis practically continuons, even Y though the throttle-valvebe closed andthe y75 p -i engine motionless.- lt-has been found, howf our invention, whicnis connected theretoy are shown yin elevation. f In internal construe#v 5o' tion and' arrangement'theydo not differfrom' the ,corresponding devices shown in section:

Y on the right ofthe' bodyof the lubricaktom the throttlewalve is opened and `s te'ajr'nadmitt-e'deto the steam-'chestthe small-volume of steampassin'g through the nozzle'-lcondenses within'the oil-pipes, result-. 8o ingin'aireducedpressure'y therein. 1 This reduced vpressure isnot suiici'ent to resist the 'back pressure of stearnfrointhe stearnlc'hest,

ivit-lr-the resultthatthe feedpof the lubricator becomes irregular and eventually stops alto- 8 5 gether.' This effect ofthe hack pressure we overcome in the 'following ,simple and 'reliable manner f To each delivery end of the lu bricator is;att-achedv avcas'ing tt, whichat. its

. delivery end e isfto be'connectedtof the tal- 9o lov:I .pipe,' (indicated at 06,15 leading to'- the" steain-chestof the cylinder to be lubricated.

. This'casing is provided lini: err1ally with a very small constantly-open portfor passage for af continuous currentofjsteam'and oilj'in limited,` 95A quantity 'from the lubricator into the talloW-' pipe and with an #lndependent'and separate' valve-controlled by-pas'sage which when' openl the by-passage. The lower and reduced end I supply of steam and oil'will pass tothe tallewvarious ways. We prefer for this purpose lone hand, and, on the other hand, communiywill furnish an' increased current of steam and oil from the lubrieator to the tallow-pipe. These two passages with which the casing is internally provided vcan be formed therein in to use the centrally and longitudinally perforated plug or-nozzle'p', usually called the choke-plug, which screws tightly''nte the partition-wall o of the casing and has a 'very small opening orpoitp in its lubricator endthat is to say, its end nearest the lubricator. This furnishes the constantly-open restricted port or passage for the continuous minimum flow of steam and oil to the tallow-pipe. The by-passage for the increased supply of steam and oil is furnished by thev cavity b, which .opens 'into the interior of the casing, on the cates with the delivery end e of the casing through a cored or drilled passage c, which is formed in the body of the casingaud'opens into the delivery end e thereof at a point be-` yond the partition-wall o, Thus through the by-passage b c the lubricator end d of the casing is put in direct communication with its delivery end e. At the point where the cav. ity b opens into the interior of the casing it is provided with a valve-seat to receive the valve f, by which communication through saidopening is controlled. The stem or spindle of this valve passes through andtightly fits in a guide plug or partition g, screwed into the interior of the casing, the stem being capable of -lengthwise movement in said plug to permit the valve to open and close of the valve-stem passes through a sensitive iiexjblel diaphragm i, of spring-metal or any other suitable material, and-.is tightly held thereto by means of the clamp-nut h, and the diaphragm at its periphery is tightly clamped tlegige saidange.

Normaly the valve f is in closed position, being thus heldv when the engine is standing still orvrunning downgrade with no steam in the cylinders by the steam from the equaliz-- ing-p-ipes M`, which steam will press against the under surface of valve f and hold it Ato its seat, thus closing the by-passage between the lubricator and delivery ends d e of the casing. Under these conditions onlyy the minimum pipe, this lsupply being furnished through the ehoke-plug p.v l y In order to open the valve f to furnish increased supply of steam and oil ,through the by-passage b c when required, the.space in the casingabove the sensitive diaphragm 'il and between" it and the plug or partition g above `shouldbel putin communication with/ the talloW-pipe, so that the back pressure in that pipe whenever it exists may act on the diaphragm to depress it, and consequently to move the valve in a direction to open the bypassage. Such communication manifestly can own invention is as follows:

be established in various ways. Forl thispnr-y pose wein the present instance provide for such communication by forming the `steinA or 7g spindle of valve f with a longitudinal central" by-passage for admitting back pressure from the tallow-pipe 'to'act u pon the diaphragm i,

as well as for furnishing the increased sup-j ply of steam and oil from the lubricator to the tallow-pipc. v

When valve if is closed, the lnbricator, as above indicated, will operate as an ordinary lnbricator, with a fixed outlet-nozzle. When steam, howcve r, is'admitted into the cylinders, it will pass back toward the lubricator through the tallow-pipe and,`passingthrough the bypassage c b and passages m and n, will press against the upper surface of valve f, as well as against the upper surface of diaphragm i, with the result that valve f will be moved from its seat. In this case in addition to the small hole p the by-passage b c will be open for the passage of steam and oil into the cylinder, and the increased volu me of steam thus furnished vwill etfectually overcome the retarding effect of 'the baci; pressure from the. cylinder. In consequence ofthe fact-that the increased steam by-passage forms also an increased oil-passage the feed of the lubrieater will not only not be retardedwhe'n steam is admitted into the steam-chest, but the feed will increase in rate with increasing pressure in the s team-chest, whichv is very desirable in 'locomotive practice. l

As usual in this class of lubricators ahandi oiler fr is provided,by means of which the cylindex-s and valves may be oiled on adowngrade in. case the sight-glasses become .disabled. We find it convenient and desirable tol mount this hand-oiler on the casing a and to put it in communication with the tallowpipe through the medium of by-passage b'c, as shown in the drawing.

Having described our invention and the manner in which the same is or may be carried 'into effect, we state,in conclusion, that we'do not claim, broadly, in a lubricating ap-4 paratus provided with suitable boiler, oy1in' der, and equalizing-pipe connections a eas- 'in located at and communicating with the de ivery'end of the lubricator, provided with a very small permanentlybpen passage for a continuous ilow of steam and oil in restrict- `ed quantity from the lubricator into the tal- IIO low-pipe and with a valve-controlled by-pas vsage separate and distinct from the minimumsuppIypermanently-open passage for permitting an increased dow of steam and oil from the lubricator through the casing into the tallV w,- ipe; but v hat we do claim herein as new and of ou 1. In alubricating apparatus provided with l suitable boiler, cylinder and equalizing-'pipe connections, a casing communicating with the delivery end 'of the lubricator provided with a stationary choke-plug for minimum continuous fiow of steam and oil from the'lubricator into the talloW-pipe, a by-passa'ge distinct andseparate from the minimum-supply permanently-open passage in the chokeplug for permitting increased flow 'of steam and oil from the lubricator through the casing, and a valve for controlling said by-passage, separate from and independent of the choke-plug, and adapted to be operated by the back pressure from the tallowpipe,subv stantially as and for the -purposes hereinbefore set forth. v

2. lThe combination with the casing a and the by-passage therein, of the valve f for controlling said passage contained in said casing, v

and having its stem movable in a guide par- -supply* portl p, and the separate and indecommunicating-passage between the tallowpipe and the space'or chamber in the casingv above 'the diaphragm, substantiallyl as yand for the purposes-hereinbefore set forth.
